this one has no storage though either, so I guess nowhere to run the shell from , unless you can set it up to run
all from the wifi (so it's whole file system runs from a "host" pc transparently for R4)

[edit] oh but it seems that no company has released one already , sigh... [/edit]

From the looks of it, cards like this have been around since about 2006 (according to a google search for microsd wifi) but none of them have any storage space, this could be down to the limited space in the actualy card itself.

It would be nice if it did have some space in there. Oh and as for using it to interface directly with a PC for it's data instead of as a storage card, the current crop of wifi enabled microSD cards need windows to work...
